React Router

React Router is a standard library used for routing in React applications, enabling navigation between different components without triggering a full page reload. It manages URLs and renders the corresponding components, effectively creating the illusion of multiple pages within a single-page application.

The library is actively maintained by the team behind the Remix framework, specifically Ryan Florence and Michael Jackson. Recently, the developers announced that Remix and React Router will be merged together starting with React Router version 7.

Standard browser routing requires a server request to fetch a new HTML document every time a user navigates to a new URL. React Router intercepts these requests and instantly renders the necessary JavaScript components on the client side, providing a much faster and smoother user experience.

In React Router version 6 and later, nested routes are implemented using the `<Outlet />` component within the parent route's element. You define the child paths inside the parent's route configuration to render them within that specific layout.
